VALVE-ACTUATING DEVICE.

Specification of Letters Patent.

Patented Apr. 27, 1915.

Application filed May 1, 1912. Serial No. 694,540.

To all whom it may concern Be it known that I, HANS Z. NELSON, a citizenof the United States, and a resident of Albert Lea, in the county ofFreeborn and State of Minnesota, have invented certain new and usefulImprovements in Valve- Actuating Devices, of which the following, whentaken in connection with the drawings accompanying and forming a parthereof, is a full and complete description, suflicient to enable thoseskilled in the art to make, understand, and use the same.

This invention relates to valve actuating mechanism particularly adaptedto close the valve, at a determined time, which controls the supply ofgasolene to vapor generating devices. And the principal objects of theinvention are to obtain a device which is suitable for use in streetlighting incandescent vapor lamps; and which may also be used in whatare known as central generator incandescent lighting systems.

To accomplish the purposes sought by me I have embodied my invention ina construction which is simple, easily understood and operated, andwhich is not liable to get out of order.

In said drawings Figure 1 is a front elevation of the device, and of agenerating de vice, showing the casing of said generating device insection and showing the casing of the timing element of the device inside elevation. Fig. 2 is a rear elevation of said device. 1F ig. 3 isan isometric view of a valve stem, the upper end of a lever, the lowerend of an additional lever, both loosely mounted on said stem, and of abase which is rigidly mounted on said stem. Fig. 4 is a side elevationof the several parts which are illustrated in Fig. 1, with said casingof the generating device in elevation. Fig. 5 is a horizontal section online 5-5 of Fig. 4, viewed in the direction indicated by the arrows.Fig. 6 is a horizontal section on line 6-6 of Fig. 4t, viewed in thedirection indicated bythe arrows. Fig. 7 is a rear elevation of saidcasing of the timing element and of the lever operated thereby, andFig.'8 is a top plan view of a portion of said casing and lever.

Similar letters refer to similar parts throughout the several figures ofthe drawing.

Before describing the device embodying this invention a briefdescription will be given of a vapor generating device and accessorieswhich are controlled by the device embodying this invention.

A is a casing, consisting of part a and part a which is hinged to saidpart a by hinge a.

a is the bottom of easing A.

B is a standard which is provided with horizontal member 1), verticalmember 6, and base 6.

C are screws attaching base 6 to wall Z.

D is a filter tube, cl is filtering material, d, is a screw threadedstem, cl is a disk or piston on stem d, d is a cap on tube (Z and el isa packing nut. When stem d is turned disk cl is advanced and filteringmaterial d is thereby compressed.

E is a gasolene supply pipe arranged to discharge into filter tube D.

N is a vapor generator and G is a connecting pipe between filter tube Dand said generator N.

The device embodying this invention is constructed as follows: F is avalve which is provided with stem zterip 7. Base H is provided with thearms I is a lever which is loosely mounted on said stem f. l/Vhen saidvalve F is open the lever I is necessarily raised into substantially theposition thereof which is illustrated in Figs. 1, 2, 3 and hand restingagainst the abutment which is illustrated in said Fig. 4. Lever I isprovided with the horizontal part i, which is located or positionedbetween the arms h, h of base H.

I is a weight which is secured on lever I, in an adjusted position, byscrew 1'. When lever I is resting against the projection or abutmentwhich is illustrated in Fig. 4, it is on or slightly over the center, ofthe axial line of stem f,'and hence remains in said raised position.

J is a lever which is loosely mounted on stemf, and said lever isprovided with the part or portion j, which extends into the path ofmovement of part 2' of lever I, (see Figs. 2 and 3).-

K is a bell crank which is pivotally mounted on fulcrum 76.

K is the shell or casing of the timing element of the device, (saidtiming element not being shown), and 7c is rigidly secured to saidcasing, (see Fig. One end of lever J H is a base which is rigidlysecured to said is attached to the end of one of the arms of bell crankK, by loop j and screw 10?.

L is an arm or lever which is attached to bell crank K by pivot 70. V

L is a sharp edge on the under side of lever L, and L. is aweight'secured onsaid lever. M is the face of said shell K, and m is thekey by means ofwhich the spring (not shown) for actuating said timingelement is wound. M is a shaft or spindle of said timing element, andrevolves once in an hour. baid shaft or spindle Mis provided withexternal screw threads, (see Fig.8.) '1

M is a set bolt in arm or lever L. To set the timing device one end ofset bolt M is forcing it around on stem f. After lever I has commencedto turn, and as it gains some momentum, the horizontal part 2'therebrought ,into contact with the casing K when arm or lever Lislaidon'shaft or spindle M, with the sharp edge-L in engagement with theexternal screw threads on said'shaft; and hence, said bolt 3 is so 7adjusted in said lever L that the requisite number of revolutions ofsaid'shaft or spindle will occur before said leve'r'Lis discharged, fromsaid shaft, (by'the turning of said shaft); When said lever L isdischarged from. said shaft the weight L turns said lever J "on itsfulcrum is, thus moving crank K and turning lever J on stem'f of thevalvel'F. The turning of said lever-J turns lever I, by part j of saidlever J coming into contact withsaid lever I and -Fof"comes in contactwith. the arm 72, and
